Hi and welcome to the forum from Scotland. I think you will find you have made a wise swap trading your Beemer for a 300C - they are over-rated and over-priced. This whole site is full of information on our cars - browse about and see for yourself then come back and ask any specific questions - they are always answered as this is one very friendly site.
Welcome to the 3CF community! Can't wait to hear about your own personal experience once you have the SRT in your hands. Just keep reading as much as you can on this forum. Members have shared some incredible stories, helpful installations (great DIY threads), beautiful modifications, and sometimes just fun, idle chat!
